My 72 y/o mother was diagnosed with pleural infusion (a case where the lungs accumulated water) and just undergone thoracentesis and bronchoscopy. Actually, prior to these she had just lost her appetite and until now she couldn't eat regularly. I really don't know what to do. The doctors didn't give any medications to increase her appetite. My mother is loosing lots of weight and its very alarming for me. Thank You.
